FOUNTAIN-PEN.

" lication filed October 16. 1907. Serial No. 397,689.

To all whom it may concern:

Allegheny, in the county of Allegheny and State of Pennsylvania, haveinvented new and useful Improvements in FountainPens, of which thefollowing is a specification.

This invention relates to self-filling fountain pens of that typecontaining a compressi ble sack or reservoir disposed within the handleof the pen.

The invention has for one of its objects to improve and simplify theconstruction and operation of devices of this character so as to becomparatively easy and inexpensive to manufacture, and thoroughlyreliable and efficient in use.

A further object of the invention is the employment of animproved meansfor feeding ink from the sack to the reservoir without danger of the inkbeing drawn into the sack from the pen when pressure on the sack isremoved.

A further object of the invention is the provision of a fountain penconsisting of a tubular handle from which thesack is readily removablefor the purpose of re-filling, cleaning the feed tube or the like.

With these objects in view and others, as will appear as the descriptionproceeds, the

invention comprises the various novel features of construction andarrangement of parts which will be more fully described hereinafter andset forth with particularity in the claims appended hereto.

In the accompanying drawing, which illustrates one of the embodiments ofthe invention, Figure 1 is a side view of the fountain pen intended moreparticularly for desk use. Fig. 2 is a view of the sack and feed tuberemoved. Fig. 3 is a side view, of the tubular handle of the fountainpen designed for pocket use. Fig. 4is a side viewpartial1y in section ofthe pocket fountain pen. 5

is a side view showing the outer tube appliedv to the pen to serve as acap therefor.

Similar reference characters are employed to designate correspondingparts throughout the several views.

Referring to the drawing, and more particularly to Figs. 1 and 2, Adesignates a tubular handle open at both ends and having pen-holdingjaws of any approved construction for receiving a steel or gold pen 0.Extending longitudinally of the handle or grip piece A is a rubber tubeor sack D closed at the end 1 and having secured in its upper end, thefeed tube 2 that has a bushing 3 applied thereto and secured in positionby a band 4 encircling the sack and frictionally holding the feed tubein the bushing, which bushing is preferably of rubber orothercoinpressible material.

The feed tube 2 is formed at its outer end with an integral tongue 5that may be flat or concave from the outlet 6 of the tube andterminating against or close to the underside of the pen for the purposeof holding the ink against the pen at a suitable distance from theoutlet 6 to prevent the ink from being drawn back into the sack whenpressure is relieved from the latter at the completion of the ejectingoperation. The tubular handle A is provided with a slot 7 located atsuch a point as to enable the thumb to in position for writing, so thatwhenever the pen becomes dry, a slight pressure of the thumb will besu'l'licient to eject ink from the sack' to the pen. The pen can befilled by removing the sack together with the feed tube from the tubularhandle or body A for completely deflating the sack by pressing the samebetween the fingers. While the sack is so compressed, the feed tube isdipped into a vessel of ink so as to draw in a charge by the expansionof the sack when the pressure thereon is relieved. If, however, it isnot desired to remove the sack from the body A, the sack can becompressed by inserting the finger into the slot 7 for depressing theadj acent part of the sack and suflicient ink can be drawn into thelatter when the pen is inserted into a bottle or ink and the fingerremoved from the sack. Enough ink will be drawn in in this manner towrite about four hundred words before re-charging will be necessary. Inthe modification shown in Fig. 8, the sack is mounted in a tubularholder E that has a slot 8 of substantial length so that a considerableportion of the sack can be compressed therethrough, it being understoodthat the sack is not intended to be removed from the holder. The holderis contained in a casing or handle piece F which is slidable thereon andhas a slot 9 through which the sack is exposed and by means of which thethumb can be inserted for compressing the sack sufficiently to dischargeenough ink to wet the pen. One end of the handle piece or casing F isclosed so that the said piece can be removed and applied over the pen soas to protect the same, as shown in Fig. 5 and thus rendering thefountain pen suitable for carrying in the pocket. It will thus be seenthat a selflling fountain pen is roduced in which the feed of ink can bede ivered directly to the pen point and without any danger of the inkbeing drawn back into the sack when the thumb is removed from thelatter, and furthermore, there can be no leakage or overflow while usingthe fountain pen, and steel, gold or other metal pens can be readilyused, the feeding of ink being always under the control of the thumb ofthe user.

From the foregoing description, taken in connection with theaccompanying drawing, the advantages of the construction and of themethod of o eration will be readily a parent to those skilled in the artto which t 1e invention appertains, and while I have de scribed theprinciple of o eration of the invention, together with t e device whichI now consider to be the best embodiment thereof, I desire to have itunderstood that the device shown is merely illustrative and that suchchanges may be made when desired as are within the scope of the claims.

Having thus described the invention, what I claim is 2- 1. A fountainpen comprising a tubular handle )iece forming a casing, a compressibleink-hol ing element therein, a pen attached to the handle piece, a feedtube connected with the ink-holding element and having its outer endspaced from the pen, and a tongue connected with the outer end of thetube and curved toward the pen from the side of the tube opposite fromthe latter for conducting the in: from the tube to the pen, theink-carrying surface of the tongue being smooth and straight intransverse cross section.

2. The combination of a handle piece, a

pen secured thereto, an ink feeding tube dismovab le through either endthereof andhaving one end normally projecting out of the said piece, anink feeding tube connected with the element and projecting from theopposite end of the handle piece, and a pen secured to the handle piece,there being a slot in the handle piece for permitting the element to becompressed by the finger of the user.

In testimony whereof I afliX my signature in presence of two witnesses.
